After having my first child in 2013, I literally wanted to kill myself. I knew being a new mother would be a challenge, but I didn't know it could be that bad. I took a PPD test and it was positive. I am one of the 950,000 parents who suffer each year. I am developing a mobile app for PPD sufferers, so that with the press of a button, a live, qualified health practitioner will be there to council them through their darkest hours.
